SPECIFICATION forming part of Letters Patent No. `608,284, dated August 2, 1898.

i Application liled May 29, 1897. 4Serial No. 638,752. (No model.) i

T all whom it may concern,.-

Be it known that I, JosEPH GREGORY@ citizen of the United States, residing at New York, in the county of -New York and State of New York, have invented a new and useful Lamp-Burner, of which the `following is a specification.

A general complaint against the use of lamps and heaters using oil and a wick is the escape into a room of unconsumed carbon and noxieus'odors and, gases, especially when the Iiame is turned low and at the instant of extinguishing the light. These objections also apply upon turning the wick too high, as in this event the supply of oil is greater than can be consumed by the limited current of air. Another objectionable feature met with is the frequent requirement of snufling and trimming the wick to keep it in good condition and the adjustment thereof to allow for consumption and trimming.

By this invention the foregoing enumerated objections and others are1obviated, a soft white light attained, the burner rendered practically inodorous, a nearly perfect com? bustion secured, the wick kept cool and the air fed to the flame heated in its. passage thereto and enriched with gaseous vapor, the

wick controlled in its Amovements and prevented from overfeeding and trimming not rendered necessary, andthe general construction simplified, wherebya better and clearer light results and theoil is consumed more economically. Y

Other objects and advantages are contemplated and will appear and suggest themselves as the invention in its details is fully comprehended. Hence to this and such other ends as pertain to the nature of the invention the latter consists of the novel features, details, and combination of parts,which hereinafter will be more fully set forth, illustrated, and finally embodied in the claims hereto appended.

The improvement is susceptible of'various changes in theform,proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in whichvWick-lifter. tion of the lower section of the spreader and Figure lis a vertical central section of a lamp having the improvements in operative relation. Fig. 2 is a detail view in elevation, parts being broken away, of the inner wickcasing and lower section of the spreader and Fig. 3 isla vertical central secwick-lifter. Figis a top plan view of the part shown in Figf.y Figij is a detail view lused in connection with lamp-stoves for heating purposes and" in lother situations where oil is the primary agent for producing light 0r heat and is fed to the point of combustion by means of a wick.

The lamp body` or fount lis mounted upon a stand 2 in the usual manner Vand may be of any pattern'and is supplied with a burner having a centralair-draft. The opening in the top portion of the lamp-body to one side of the burner for lilling is closed by a cap 3 in the ordinary manner.

The wick-tube comprises an inner casing 4, which passes through the lamp-body, and an outer casingh5,the1upper. end of the inner easing terminating a short distance from the upper end ofthe outer casing to give ample -clearance yfor the movement of the spreader and wick-lifter and having a hollow or annular depression a a short distance from its upper end to receive the curved ends b of springarresters o, attached to a band d, mounted upon the inner casing 4 and held in place by a bead e. The wick-space between the inner and outer casings is larger than the thickness of the Wick 6,'Whereby a space 7 is provided between the outer casing andthe Wick for the passage of the air, whereby the wick is kept cool. The outer casing is contracted at its upper end at 8 to engage with the wick G and retain it in place, the contracted portion extending over vand closing the space 7 and serving to direct the air to the end of the wick.

The spreader t) is formed with or has applied thereto a wick-lifter 10, the latter cmbracing the upper portion of the inner easing l and forming a continuation thereof. The lower portion of the spreaderis contracted or made hollow, as shown at 12, to secure the best results in the distribution of the air to the flame, and this spreader above the hollow or contracted portion 12 has an extinguisher 13. The wick-lifter has hooks 11 at its upper end, radial bars 1l, and a ring 15, the latter and the bars 14C extemlinghorizontally and the hooks 11 projecting vertically and having their bent ends extending outwardly to engage with the top edge of the wick (j to cause the latter to descend when lowering the spreader and lifter. are provided at the sides of the wick-lifter and have their upper ends g curved inward to extend across the path of the extremity of the wick-casing t to ride thereon and be projected outward into the space occupied by the wick, so as to engage with the latter and elcvateit upon moving the spreader and wieklifter upward. 'lhese teeth are integral with the wick-lifter and are formed by cutting portions therefrom and operate in the slots resulting from providing the teeth. The spreader rests upon the outer ends of the bars 11 and is heldin place by the hooks 11. The lower end of the wick-lifter is adapted to wedge between the casin g t and the wick-arresting teeth c and is limited in its downward movement thereby.

rlhe upward movement of the wick-lifter and spreader is limited by means of a loop 1G, applied to the lower end of a rod 17, which is connectedat its upper end with the spreader in any convenient way and secures the spreader and wick-lifter together. One side of the loop 16 has a series of openingsl 1S, and the other side is formed with a vertical slot 19, and the wick-raising shaft 2O has its pinion 21 operatingin the slot 1!) and the teeth of the pinion cooperating with the openings 18, so that upon turning the shaft 2O the rod 17 and the parts connected therewith are correspondingly moved up or down, according to the direction of turning the shaft. The lower end of the loop 1G is so constructed and proportioned as to engage with the shaft 20, thereby limiting the upward movement of the wick-lifter in the manner set forth through the connections between it andthe wick-controlling mechanism. After the wick 6 has once been properly adjusted upon the wieklifter, so as not to smoke when raised to the limit of its upward movement, it can never be raised too high and is limited in its upward movement bythe loop 1b' engaging with the shaft 2O in the manner set forth.

The chimney-holders 27 are secured to the gallery 2S in the ordinary manner, and this gallery has an outer flange or bead 29, which Teeth f forms a support for a reflector 30, which is an annulus and may be of glass backed in the usual manner, whereby a reflecting-surface is attained, or maybe of highly-polished metal, and this reflector may extend horizontally or in any direction desired, so as to secure the objects in view, and may form a holder for the shade.

The upper portion of the shell hof the gallery is contracted and terminates about on a level with the outer casing 5 and forms therewith a narrow space 33, whereby the air is directed upon the flame close to the upper end of the wick. rlhe sides of the spreader are perforated from the top to the plane of the ends of the parts 5 and 71 and inasmuch as the relation of the spreader and wick remains fixed the air entering the inner casing is directed toward the edge of the wick, whether the flame is high or low, thereby preserving an uninterrupted supply of air to a perfect combustion, which is essential to prevent the burner from throwing off carbon or noxious vapors. The casing 5 and shell 7L inclose a space t, and the connecting portion j is perforate, and the sides of the shell 7L have openings for the entrance of air, which enters the fount and, with the air coming in through the cap 23, passes into the space 7, formed between the wick and the outer easing 5, and rising in said space cools the wick, and at the same time is heated and becomes impregnated with gaseous vapor, and discharging upon the flame promotes and increases the combustion and materially assists in producing the soft white light peculiar to a bu rner constructed in accordance with this invention. lVhen it is required to extinguish the light, the spreader is lowered and carries with it the wick-lifter and wick, and when the extinguisher rests upon or engages with the upper end of the outer casing 5 the gases and vapors confined in the space closed by the extinguisher are condensed by the cool air entering through the body of the lamp and passing to said space through the annular passage 7, whereby no odor, carbon, or vapor is given off. The inner and outer drafts have been found sufficient in practice to carry off the ashes resulting from a consumption of the wick, therebyrenderingtrimming thereof unnecessary, and the ascending cur rent of air through the space 7 keeps the wick sufficiently cool to prevent its charring to the extent common in lamp-burners as generally constructed, thereby resulting in prolonging the usefulness of the wick. As the wick is consumed it is automatically fed by reason of the limited movement of the wick-lifter. Upon lowering the spreader the hooks, teeth, or spurs 11 engage with the top edge of the wick and cause it to descend. lVhen the lower edge of the wick-lifter engages with the teeth b, they are thrown outward and engage with the wick and arrest The teeth j move in its further descent.

ward when the top edge of the casing 4. is cleared and are forced outward when riding upon the casinge.

The combined wick-lifter and spreader is formed of two parts which are connected together by the rod 17, the latter having lateral wings fm at its upper end and a shoulder or stop n a short distance from the said upper end, the wings m extending over the top of the spreader and the stop n engaging with the lower side of the part 15, projecting across the space of the wick-lifter.

A spreader and wick-lifter formed of separable parts and connected to move together and operate in the wick-space, an operatingrod for. the wick-lifter and spreader having a loop, a shaft having a pinion to coperate with the said loop, and a wick-lifter having teeth to automatically release and engage with the wick are features set forth and claimed in an application for a like invention filed by me December 1l, 1896, Serial No. 615,342, and forlnally allowed May 7, 1897.

Having thus described the invention, what is claimed as new'is- 1. In a lamp-burner, the combination of an inner and an outer casing forming between them a wick-space, the inner casing terminatingbelow the outer casing, and a spreader and wick-lifter working together, the wick-lifter operating in the wick-space and the spreader having its sides perforated to the line of separation between the spreader and wick-lifter to supply an equal amount of air to the burning end of the wick at all adjusted positions, substantially as set forth.
